Loads only 30 topics at a time with server-side search instead

Replace all db.run(sql, [params]) calls with db.prepare(sql).run(...params)
across all source modules and test files. Also remove the node-sqlite3-wasm
import from tests/db.test.ts and update the type annotation accordingly.

Collect payloads in memory Map, flush to SQLite every 2 seconds
instead of on every message. Prevents DB lock and slowness with
high-volume brokers like Venus OS.

created and the broker subscribes to that topic for live updates.
